I run a Thieves World discussion group on FB. Lynn Abbey (she is the editor and owner of TW, which is a shared world with many contributing authors) is on it, and it is a great place to go on the upcoming TW return, as well as lots of discussion of old TW products and images of TW covers.

I have a pdf of an old website (no longer in existence, nor on the wayback machine as far as I can tell). It has ALL of the old stuff, but the book list and the RPG products, graphic novels, and the miscellaneous short stories that appeared in other sources. I will post what I can this week end, and anyone interested in the pdf (it is very large) can PM me.

Sanctuary is the name of the city, unless Lynn named it in the Green Ronin products neither the world nor the continent have a name.

Heroes of Olympus

Now you can relive the adventures of the Argonauts! You, as Hercules, can slay the
hydra! You, as Jason, can brave the crashing rocks with battered ship and crew!
You, as the sorceress Medea, can tempt a Hero's heart! But be careful not to incur
the wrath of the gods."
Heroes of Olympus by TFG (Task Force Games) in Amarillo Texas from 1982 is a
Fantasy Role Playing game, as well as a stand-alone board game with solitaire rules
and scenarios and scenarios and rules for 2 players. Created by veteran gamedesigner
B. Dennis Sustaire, it recreates mythical Greece. The game system covers

campaign rules. Complexity is moderate and game time ranges from two hours for board-game
scenarios to several evenings for campaign play.
